Cooking vessel top to prevent boil over of liquids

Abstract

A cooking vessel top according to the present invention is presented in that at least the contact surfaces of the cooking vessel top with the different cooking vessels are formed from an elastic material, especially silicone, that the passage opening or passage openings have at least one flat closure part connected to the cooking vessel top, which in the rest state not in contact with the boiling or foaming liquid essentially closes the passage opening or passage openings allocated to it and can be moved into an opening position by the opening force that develops on contact with the boiling or foaming liquid, in which the passage opening or passage openings are at least partially released and is configured and connected to the cooking vessel top so that it offers a slight resistance to the opening movement.

       7. The cooking vessel top according to  claim 1 , wherein at least the contact edges of the closure part or the closure parts essentially correspond to the shape of the cooking vessel top there. 
     
     
       8. The cooking vessel top according to  claim 1 , wherein the passage opening(s) allocated to closure part or closure parts overlap. 
     
     
       9. The cooking vessel top according to  claim 1 , wherein two adjacent closure parts are allocated to each passage opening, in which the edges of the adjacent part lie against each other or overlap in the area of the passage opening. 
     
     
       10. The cooking vessel top according to  claim 1 , wherein the closure part or parts are configured to be moved flap-like between the rest position and the opening position. 
     
     
       11. The cooking vessel top according to  claim 1 , wherein the closure part comprises at least one feature selected from the group consisting of ribs and notches. 
     
     
       12. The cooking vessel top according to  claim 1 , wherein the thickness of a closure part diminishes toward its free edges not connected to the cooking vessel top. 
     
     
       13. The cooking vessel top according to  claim 1 , wherein the closure part acts as a membrane valve, wherein a central area of the closure part is connected to the cooking vessel top and essentially closes the passage opening or passage openings in the rest state with a ring area connected to the closure part. 
     
     
       14. The cooking vessel top according to  claim 1 , wherein the closure part acts as a membrane valve, wherein individual closure parts each allocated to a passage opening are formed in a ring area connected to a central area of the cooking vessel top and, which essentially close the corresponding passage opening in the rest state. 
     
     
       15. The cooking vessel top according to  claim 13 , wherein the membrane valve-like closure part is formed as a separate component that is configured to be connected to the rest of the cooking vessel top. 
     
     
       16. The cooking vessel top according to  claim 1 , wherein the area of the cooking vessel top that has the passage opening(s) with the allocated closure part is designed as a component that is configured to be connected to the rest of the cooking vessel top part. 
     
     
       17. The cooking vessel top according to  claim 1 , wherein at least one closure part has a contact surface which at the end of movement from the opening position into the rest position with an additional contact surface formed on the edge of passage opening, preferably a sloping surface or stop knob in its movement path, enters into effective connection and therefore permits only an opening direction. 
     
     
       18. The cooking vessel top according to  claim 1  further comprising at least one feature selected from the group consisting of, ribs, notches, and knobs.
